Product Description

Product Description

Automatic Hairpin tube making machine for Air Condition 

Summary

The Long U-Type Hairpin Copper Tube Bending Machine is designed for automatic production of U-shaped tubes used in air conditioner heat exchangers.
It performs multiple processes including tube opening, straightening, chip-free cutting, and precise bending into fixed U-shape hairpin tubes.
This machine ensures stable operation, smooth bending, and consistent dimensions, making it ideal for high-efficiency automatic manufacturing of long U-type copper tubes.

Features

1. Integrated Automatic Operation:

The machine combines tube straightening, feeding, chip-free cutting, bending, core pulling, and unloading in one continuous automatic cycle: Straightening → Feeding → Pressing → Cutting → Bending → Core Pulling → Loosening → Unloading → Reset.
2. Advanced Hydraulic Bending System:

 Adopts a quantitative hydraulic pump and swinging oil cylinder for smooth bending motion, suitable for high-speed and continuous production.
3. Flexible Material Rack Options:

Available with gantry-type, single-station, or double-station electric drive material racks, meeting various production requirements and pipe sizes.

4. Reliable Straightening and Feeding Structure:

The copper tubes are straightened on both horizontal and vertical planes, while a friction synchronous belt feeding mechanism ensures stable and accurate tube delivery.

5. Efficient Rolling Cutting Design:

The external hob cutting device uses oil mist lubrication for smooth, burr-free cuts, with adjustable cutting depth for each copper tube.

6. Adjustable Hairpin Tube Length:

The machine includes a length adjustment device to easily switch between different U-tube specifications.

Application

Refrigerator Cooling System

Air Conditioner Heat Exchanger

In refrigerators, U-shaped copper tubes are used in compressor-connected condensers and evaporator circuits to transfer heat between refrigerant and air.

In air conditioners, long U-type copper tubes are mainly used in condenser and evaporator coils.
They connect multiple rows of copper pipes to form a closed circulation loop, allowing refrigerant to flow efficiently for heat exchange and cooling.
